RR-, Duchy of Warsaw, 3 pennies 1810 IS, pilot-trial issue

A rare variety with the inscription GROSZY placed tightly. This is most likely the first trojak stamp made for the Duchy of Warsaw, on which the inscription GROSZY was compressed - the mintmaster at the time did not yet know the diameter of the disc on which this denomination was to be minted. This trojak can be regarded as a kind of trial issue. The rarest vintage of the troy in a type practically uncommon on the market, unlisted at WCN auctions. Berezowski values this variety 5 times higher than the basic one for this vintage and 7.5 times higher than the popular Duchy of Warsaw trojaks.
